Abstract

A variety of approaches was used to test a number of possible hypotheses about the origin of 2 ridges on the eastern slopes of the Mt Allen, southern Stewart Island. These include topographic and spatial positioning, geomorphology, sedimentology and palaeoclimatological extrapolations to reconstruct 2 small former cirque glaciers with equilibrium line altitude (ELAs) of c. 600 m. It would appear the 2 ridges reflect a glacial origin, the glaciers interpreted as forming during the Last Glacial Maximum (LGM) in New Zealand. Whilst glaciation during this time (18-19 ka) was extensive in the Southern Alps, the restricted nature of glaciation on Mt Allen suggests the low altitude restricted glaciation to niche sites on the lee side of upland areas
